Well, some things you should do.

McAfee is a well know network crasher. Uninstall McAfee Using McAfee Removal Tool.
Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Download and install those, and then run full system scans with both of them, one by one.

Also the network driver is kinda old.

Code:

Name    [00000021] Realtek PCIe GBE Family Controller
Driver    c:\windows\system32\drivers\rt64win7.sys (7.46.610.2011, 526.60 KB (539,240 bytes), 6/10/2011 6:34 AM)

Update it from Realtek.

Moreover, Daemon tools is not a safe program. It causes BSODs every off and on. Better you uninstall it.

Let us know the results.
